How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.
- Moderate: Can be significant — usually manageable with monitoring.
- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
You've been prescribed amitriptyline (a tricyclic antidepressant) along with sodium salicylate (an aspirin-like pain reliever). Taken together, these two can raise your risk of bleeding. Both medicines can affect how well your body forms clots, so combining them may make bleeding a bit more likely, including rare but serious bleeding.
This doesn't mean you can't take both. It just means your care team may want to keep a closer eye on you. Watch for things like unusual bruising, bleeding gums, nosebleeds, or dark stools, and report a bad headache right away. Please don't stop either drug on your own. Talk with your pharmacist or doctor about the best plan for you.
Effect: Increased bleeding risk when a tricyclic antidepressant (amitriptyline) is combined with a salicylate/NSAID-type agent (sodium salicylate), including reports of intracranial hemorrhage within 30 days of concomitant use.
- Direction: Additive/synergistic bleeding risk (increased effect).
- Mechanism: Unknown; salicylates impair platelet function while TCAs may contribute independently.
- Evidence: Established. Onset: Unspecified.
- Severity: Major.
Management: Use with caution. Monitor for signs of bleeding (bruising, GI bleeding, epistaxis, neurologic changes suggesting intracranial hemorrhage). Neither agent is dose-titrated by a fixed rule here; individualize therapy and consider alternatives if bleeding risk is high.
What happens
An increased risk of bleeding
Interaction Deep Dive
Coadministering NSAIDs with tricyclic antidepressants warrants caution, since this combination may raise the risk of bleeding, such as intracranial hemorrhage occurring within 30 days of using them together1. During concurrent administration of NSAIDs and tricyclic antidepressants, watch the patient for indications of heightened bleeding.
Why it happens (mechanism)
Unknown
How to manage this interaction
The main step here is watchfulness. Your care team knows about this combination and can manage it safely.
- Keep taking both as prescribed unless your doctor or pharmacist tells you otherwise.
- Watch for bleeding signs: easy bruising, bleeding gums, frequent nosebleeds, blood in urine or stool, black tarry stools, or vomit that looks like coffee grounds.
- Seek urgent care for a sudden severe headache, confusion, weakness, or vision changes.
- Ask your pharmacist or prescriber whether a different pain reliever might be a better fit, especially if you also take other blood thinners.
Your team may monitor you more closely and tailor your medicines to keep you safe.
Management is individual — confirm any change with your pharmacist or prescriber.
Literature reports
1 report — tap to read
a) The combined use of NSAIDs with antidepressants, including tricyclic antidepressants, SSRIs, serotonin-norepinephrine reuptake inhibitors, and MAOIs, produced a heightened risk of intracranial hemorrhage within 30 days of concurrent use when compared with antidepressant use alone. No significant difference in this elevated risk was found among the antidepressant drug classes; however, an increased risk was seen in male patients relative to female patients 1.
